Answer:
the pyramid is 120 and the cylinder is 16
Step-by-step explanation:
because 10x12 is 120 and on the cylinder is 4cm on the length and the 2cm is only half way on the top part and if it's 2cm on the top then the other half is also 2cm and 2cm plus 2cm is 4cm and so 4cmx4cm is 16 hopefully this helps im in elementry school and I love the math about volume so hopefully this helps if it doesn't then i'm sorry remember i'm only in elementry school
An even function can be reflected about the y axis and map onto itself
example: y=x^2
an odd function can be reflected about the origin and map onto itself
example: y=x^3
a simple test is the following
if f(x) is even then f(-x)=f(x)
if f(x) is odd then f(-x)=-f(x)
so
even function
subsitute -x for each and see if we get the same function
remember to fully expand these
g(x)=(x-1)^2+1=x^2-2x+1+1=x^2-2x+2 is the original one
g(x)=(x-1)^2+1
g(-x)=(-x-1)^2+1
g(-x)=(1)(x+1)^2+1
g(-x)=x^2+2x+1+1
g(-x)=x^2+2x+2
not same because the original has -2x
not even
g(x)=2x^2+1
g(-x)=2(-x)^2+1
g(-x)=2x^2+1
same, it's even
g(x)=4x+2
g(-x)=4(-x)+2
g(-x)=-4x+2
not the same, not even
g(x)=2x
g(-x)=2(-x)
g(-x)=-2x
not same, not even
g(x)=2x²+1 is the even function
